So, I transplanted an NA S5 into my FB and it runs but I ma having trouble. Sadly when I pruned back the wire harness for the engine, I removed the wires for the check engine light. I want to put them back so I can read the code right now and any other problems in the future. I have done quite a bit of searching, but cannot find in the wire schematics the color of the wire to jumper up by the leading coil. If someone could give me the color of that wire, it would be greatly appreciated. From the ECU pinout in the FSM I think that the ones I need are 1D (Self Diagnosis Checker) yellow, 1E (Malfunction Indicator Lamp) yellow w/ blue stripe, and 1F (Self Diagnosis Checker) yellow w/ black stripe.

 

Ill go take a look at my car.
Its a S5 turbo but it should be the same color.

 

Thanks, I appreciate it.

 

ok......my wire color is either brown or orange lol.
its a solid color too, no stripe....

I hope that helps a little haha

after further reading, its pin 1i

 

Thanks, where did that diagram come from? I've been looking for ones like that. All I could find is what is in the S5 wiring pdf.

 

Series five diagrams also show it as a ORANGE wire. See series five wiring diagrams.

 

Sweet. Now that I know what I'm looking for I can finish this thing up and hopefully it will run better. Thanks for the help guys. I don't know how many hours I spent looking though diagrams and pinouts and I missed it.
